  <p class="para">
   Returns an array of strings, each of which is a substring of

  <p class="para">
   If there are <span class="replaceable">n</span> occurrences of

   there is no occurrence of <code class="parameter">pattern</code>, an array with
   only one element will be returned. Of course, this is also true if
   <code class="parameter">string</code> is empty. If an error occurs,
   <span class="function"><strong>spliti()</strong></span> returns <strong><code>FALSE</code></strong>.
